There are some things in life that are beyond our understanding. No matter how many questions we ask and answer, it will never be enough for us to completely grasp their true meaning. It’s like trying to step on our own shadows. We could twist our bodies from all possible angles, but our shadows will always remain beyond our grasp. Sometimes, we encounter these shadows unexpectedly, lurking behind us or looming over our heads like a guillotine, just waiting to strike when we feel that nothing could go wrong.
